I’d like to set up capistrano to send an email whenever we do a  
deployment. Just start an SMTP session with localhost and shoot off  
the email. I have all the code to do that actually, I just don’t know  
how to run some Ruby code on the deployment server. Anyone know how  
to do that, or do you have an email recipe?

Pat

Hey Pat-

Here is a method you can use to run ruby code on the remote server:

def ruby(cmd, options={}, &block)  
temp\_name = random\_string + “.rb”  
begin  
put(cmd, temp\_name, :mode =\> 0700)  
send(run\_method, “ruby #{temp\_name}”, options, &block)  
ensure  
delete temp\_name  
end  
end

# then in a recipe:

task :foo do  
ruby “puts ‘hello world!’”  
ruby \<\<-RUBY  
1.upto(10).do |i|  
pust i  
end  
RUBY  
end

Cool, thanks, that worked. Until I needed to load up some stuff from  
the rails environment. Decided to use ActionMailer instead of just  
doing the SMTP connection. Anyway, I created a cap plugin:

module CapistranoRunner  
def runner(cmd)  
run “#{release\_path}/script/runner "#{cmd}" -e production”  
end  
end  
Capistrano.plugin :runner, CapistranoRunner

and then to use it it looks like

task :after\_deploy do  
runner.runner “CapistranoMailer.deliver\_deploy(:revision =\>  
#{revision})”  
cleanup  
end
